1. What property of matter refers to the amount of space occupied by an object and is measured in cubic units?
- A. Mass
- B. Density
- C. Weight
- D. Volume
Correct answer: d
Rationale: Volume is the property that refers to the amount of space occupied by an object and is measured in cubic units such as cubic meters or cubic centimeters.
2. How does the mass of an object affect its inertia?
- A. Mass has no impact on inertia
- B. Higher mass increases inertia
- C. Higher mass decreases inertia
- D. Mass influences gravitational force, not inertia
Correct answer: B
Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.
3. The Becquerel (Bq) is the designated unit for quantifying:
- A. Electron volt (eV) measurements of energy
- B. Radioactivity
- C. Electric charge (Coulombs)
- D. Force (Newtons)
Correct answer: B
Rationale: The Becquerel (Bq) is the designated unit for quantifying radioactivity. Radioactivity is the measure of the rate at which radioactive atoms undergo nuclear decay and emit radiation. One Becquerel is equal to one nuclear decay event per second. This unit is named after Henri Becquerel, the scientist who discovered radioactivity. Therefore, option B, 'Radioactivity,' is the correct answer. Electron volt (eV) measurements of energy are quantified using a different unit, electric charge is measured in Coulombs, and force is quantified in Newtons, making them incorrect choices for this question.
4. What is the relationship between work and the displacement of an object?
- A. Work depends only on the force applied, not displacement
- B. Work is directly proportional to displacement
- C. Work is inversely proportional to displacement
- D. Work is unrelated to displacement
Correct answer:
Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.
5. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:
- A. Was bored and disinterested.
- B. Found the story confusing.
- C. Was completely absorbed and engaged.
- D. Disagreed with the speaker's message.
Correct answer: C
Rationale: "Captivated" suggests the audience was completely held by the speaker's story.
6. Julius stresses the importance of promoting ‘esprit d corps’ among the members of the unit.
- A. “Let’s work together in harmony; we need to be supportive of one anotherâ€Â
- B. “In order that we achieve the same results; we must all follow the directives of Julius and not
- C. “We will ensure that all the resources we need are available when needed.â€Â
- D. “We need to put our efforts together in order to raise the bar of excellence in the care we
Correct answer: D
Rationale: The correct answer is D because it emphasizes the idea of collective effort and striving for excellence, which aligns with promoting 'esprit de corps' - a sense of unity and camaraderie among group members. By working together and combining their efforts, the unit can enhance the quality of care they provide. This fosters a positive team spirit and encourages collaboration. The other options do not directly address the concept of 'esprit de corps' or the importance of unity and teamwork within the group.
